31 Claims.

This invention relates to roofing and siding elements, to surfacing coverings thereof and to methods of making such material, and is a division of my copending application Ser. No.

484,079, filed Sept. 24, 1930, now Patent 2,006,270,

June 25, 1935.

It is one of the objects of the invention to provide improved roofing and siding elements manufactured from the usual composition material,

a granular surfacing, for instance, of slate or similar materials held to the base by a suitable adhesive binder.

It is the further object of this invention to provide roofing and siding elements of the aforesaid material which are formed and cut in a novel manner so as to be capable of simulating a pluralityof figures when applied to a building, said elements being particularly adapted to simulate brick-like figures separated by mortar joints.

Another object of the. invention is to provide improved roofing and siding elements of composite structure to furnish maximum. protection in weather exposure. A further object of the invention is to provide composition building material of the class described which, due to the plurality of thicknesses utilized therein, possesses unusual rigidity at the exposed portions and therefore effectively withstands the action of wind thereon.

A more particular object of the invention is to provideroofing and siding material with a tab formed edge in which the tabs are separated by recesses that extend through the entire section of the material, and in which the tab portions are made massive by a composite structure of strata simulating the figures tobe formed in assembly and, moreover, in which the body portion of the element is a contrasting effect from the exposed tab portion so that the elements are adapted to be laid to create definition line effects between the figures formed by the tab portions.

An additional object is to provide roofing and siding elements of high insulating character through the provision of a strata of cork or material of similar insulating characteristics in the element structure.

A more specific object of the invention is the provision of means to definitely and uniformly space elements in one course form those in another so as to form uniform definition lines between the tabs of the elements in adjacent courses.

for instance, a waterproofed fibrous base having The invention is further directed to a novel means of forming elements of the aforesaid character from a continuous sheet without substantial waste and to the provision of roofing and siding elements which are relatively simple in construction, attractive in appearance and well adapted for the purpose described.

With the above and other objects in view the invention consists in the improved roofing and siding elements, the improved manner of assembly and method of manufacture and all parts and combinations thereof, as set forth in the claims and all equivalents thereof.

Refeiring to Figs. 1-3 of the drawings, it will be seen that the element herein illustrated comprises a body portion 2 having a plurality of spaced apart portions 4, preferably integrally connected to the body portion and preferably of the same width as the body portion. As indicated in the drawings the said portions may comprise folded over tabs. Between the body portion and the spaced apart portions is positioned a layer of filler material 6 which may be of any fibrous or mineral material that will improve the insulating qualities of the elements, but preferably is of cork. The filler material is preferably, as illustrated in Fig. 3, of sheet-like character and positioned so that it projects at one end as at 8, leaving a recess Ill or receiving space at the other end. The spaced apart portions 4 and the layer 6 are preferably cemented or otherwise secured to the body portion 2 to form a unitary structure. As will be readily evident from Fig. 3, when the elements are assembled the projection 8 of one element will be positioned to occupy the space or recess ll) of an adjacent element and may form an interlocked locking engagement of mortise and tenon character. The elements may thus be interlocked in a course without marring the surface of the assembled elements in the manner heretofore evident where locking means have been employed. Also the structure is likewise one of substantial rigidity; the spaced apart portions 4 which also form exposed portions of the elements when assembled in lapping courses will resist any tendency to lift, due to action of wind or weather.

. Further, it will be evident that such rigidity promotes easy handling and assembly. Elements such as here illustrated are also particularly adapted to simulate clap board siding and when the additional insulating layer is employed a siding of high insulating character results.

Referring now to Figs. 4-13 in which are illustrated elements having tabs projecting from a body portion wherein the tap portions form a composite structure, and are defined by slots or recesses entirely through the. material between the tabs, it will be noted that the elements are adapted to take various formations and a face portion of the tab structures define a completed figure. In Figs. 4 and are illustrated elements cut from a web l2. The web, as will be evident from Fig. 4 is out along a longitudinal intermediate line I4 and along irregular transverse lines l6. Slots or recesses l8 are cut out in each direction from the longitudinal line l4 forming sections IS, the slots on one side of the lineibeing preferably staggered with respect to the slots on the other side. Portions of the web material are formed into fingers connected with the web and are adapted to be folded. The fingers as illustrated may be formed by the same cuts creating the slots l8. The face of the web in Fig. 4 may be uncoated, or it may be covered with a layer of asphalt alone or with asphalt and crushed mineral material, the latter, if used, being preferably of a contrasting color from that used on the other side or face of the web. The body portion and a portion of the sections l5 to the line of fold 22, of said other side or face of the web may be unsurfaced,'or such portions may be coated with asphalt. The remainder of this face of the ,web, that between the lines I 4 and 22 of Figure 4, is preferably coated with asphalt and. with crushed mineral of a color which contrasts with the reverse side of the web. The elements formed from each side of the web are preferably folded along the lines 22 of the sections l5 of Fig. 4 to form composite tabs, and the portions .20 remaining at the ends of the slots 3 are folded upwardly adjacent the face of the web l2 to form spacing means. All of said folded portions may be cemented or otherwise secured to the body portion of the element. Thus an element is formed having a body portion l2 and tab portions 2| projecting therefrom having composite strata, lending considerable rigidity to these portions. Moreover, the structure may include means integral with the unit to space the elements ln assembly. The elements may be assembled'as shown in Fig. 5 with the lower edge 24 of one element abutting the spacing means 20 of an underlying element and determining a longitudinal depressed space of uniform width between the lower edge of said element and the overlaid portions of the sections l5 of the underlying element. This depressed space cooperates with the depressed space between the tabs 2| to set ofi the figures formed. The

folded over portions of the tabs 2| are preferably surfaced with material which contrasts with that used on the body portion l2 so that in assembly the contrast is perceivable in the horizontal depressions 26 that are formed by exposing the body portion l2 of underlying elements and through the transverse slots l8 that extend between the tabs and expose this same body surface |2. It will be understood that the disclosed element and assembly provide an extremely desirable means of forming accentuated brick siding separated by mortar bands. The shadow cast by the lower thickened edge of the overlying elements will fall within the depressed spaces formed between elements and thus greatly aid in accentuating the surface effect desired.

Were the tabs only the thickness of the body pcrtions no depressed horizontal spaces would be formed and the shadows cast by said edges would detract rather than aid the effectiveness of the bands of demarcation.

In Figs. 6 to 10 the elements are preferably cut from a web 28. Said web may, as disclosed, be out along an irregular longitudinal line 30 and along irregular transverse lines 32 to form a plurality of elements from each side of the web having, for instance, a plurality of semihexagonal portions 34, and, substantially hexagonal portions 36 projecting from an edge of a body portion 35 which may be its lower edge 38. The hexagonal portions 36 may be folded upon the body as shown in Fig. 'L with a substantially semi-hexagonal portion of thfidditional strata extending above the lower edge 38 of the body portion in this figure and the remaining portion substantially coinciding with the portion 34 connected to the edge 38 thereof.

underlying elements as to create an irregular depression across the course, which depression'as will be evident fromFig. 8, sharply sets off the adjacent hexagonal figures 36 of the various elements. The assembled effect is further accentuated when the portions 36 are surfaced with material which contrasts in color with that used on the main portion of the body. In that case inner space edges ofother elements.

there will be formed a covering of hexagonal figures separated by relatively wide definition lines of contrasting effect, which lines are also depressed in relation to the hexagonal figures to accentuate the result produced. It will of course be understood that the invention is' not limited to hexagonal figures, as other configurations may also be formed.

The elements cut from the web in Fig. 6 may also be used as shown in Figs. 9 and 10 with the projecting portions 36 positioned underneath instead of on top of the body porton 35, yet

similarly connected to the semi-shaped tabs 34 projecting from the body by, for instance, a line of fold. Elements of this character may be laid in the customary manner of applying strips as disclosed in Fig. 10 with the lower edges of the projections of one element registering with the In this manner figures of various character may be formed and heavy butt edges provided in which the additional thicknesses are included on the underside of the element.

It should further be understood that the elements of the type illustrated in Figs. 6-10 may also be manufactured with an additional tab I projection connected to the tab 36. In that case there will be a double fold and the exposed portion of the formed figures and spaces therebetween such as that in Figs. 7 and 8 will be from the same side of the web 28 of Fig. 6. Obviously, not only will tab portions of still greater thickness be obtained but the necessity of surfacing a portion of the rear of the web will also be eliminated. It is further desired to be understood that according to the manner of cutting illustrated in Fig. 6, any number of connected tabs may be formed on the element blanks with substantially no waste.

The elements of Figs. 11-13 comprise, as illustrated in Fig. 11, a blank comprising a substantially rectangular body 40 having spaced apart rectangular projections 42 at its lower edge. These projections are preferably scored along the lines 44 to permit the folding of the lower half 45 of each projection as shown in Fig. 12. The

folded portions are preferably secured in folded position and the elements are laid as shown in Fig. 13 with the lower edges of the folded projections registering with the inner space edges of an element below to create a plurality of raised rectangular or brick-like figures, the contrast being made particularly effective by the depressed space of similar character between the raised figures in a course.

In Figs. 14 and 15 are illustrated elements embodying a body portion 48 having spaced apart rectangular tabs 50, projecting from the upper edge and spaced apart ofiset tabs 52 projecting from the lower edge. The body portion 48 is cemented or otherwise secured to a backing sheet 54 and the tabs are folded toward one another as shown in Fig. 14 and are secured to the body portion. It is to be noted that between the upper tabs 50 there are spacing projections 56 which project above the folded portion of the tabs and are substantially in the plane of the body portion. At one end of the body portion a tongue 58 is formed and at the other end below the folded over tabs there-adjacent is a recess 60. In assembly the tongue 58 of one element enters. the recess 60 to properly position adjacent elements in the same course. One course of elements is laid with its lower edge overlapping the backing sheet 54 of the course below ,and abutting against" the spacing projections 55. The exposed portions of the tabs 50 and 52 are surfaced with mineral which contrast with the body portion 48 and with the backing sheet 54 so that a brick-like effect is created. 'It will be obvious that the projections 56 on. the element serve to obtain a mortar band between adjacent elements that is of uniform width throughout the course and may also be of the same width as the mortar spacing between the tabs on the elements.

It should be understood that although all of the forms have been shown as embodying a predetermined number of figures, any of said forms may be manufactured to provide continuous strips of the roofing and siding material or in roll form, the folding of the tabs in certain cases being carried out in asembly. The dimensions of the body may also be changed as desired to provide for varied thicknesses in assembly and to vary the quantity of material necessary to cover the standard roofing unit of 100 sq. ft. Moreover, the folded portions of the various units may be reinforced by the use of tape or other reinforcing means along the lines of fold.

From the above description it will be apparent that very novel roofing and siding elements have been provided, adapted to provide an insulation medium of high character, and also adapted to produce aneifect of sharply defined figures without the use of artificial means, such as paint, and by a relatively simple process. Furthermore, areas of double or greater thickness are provided by the elements in assembly and these afford additional protection against the weather. It will be obvious that various modifications and changes may be made by those skilled in the art to which this invention appertains without departingfrom the disclosed features. It is therefore desired that the invention be construed as including all equivalents and as broadly as the claims, when taken with the prior, art, may allow.
